Infantile Glaucoma(Buphthalmos) Incidence :

i. Age : present since birth , symptoms may manifest within 1-3 years of life .

ii. Sex : Boys > Girls

iii. It’s usually bilateral

Symptoms :

1- Lacrimation

2- Photophobia

3- DV

4- enlargement of the cornea

Page 5: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Signs :

1- enlargement of the eyeball

2- corneal oedema

3- deep anterior chamber

4- Lens is flattened and displaced backward

5- Sclera becomes thin and bluish

Diagnosis :

1- Raised intraocular pressure

2- Measurement of corneal diameter

3- Fundus examination

4- Gonioscopy

Treatment

Page 11: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Surgical treatment ( Trabeculectomy )

Argon or Diode Laser Trabeculoplasty

Acute congestive glaucoma

Page 13: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Closed Angle Glaucomacondition which the intraocular tension is raised due to the narrow or closed angle of the anterior chamber .

Etiology -genetic base-

1- small eyes

2- anatomically narrow angle

3- shallow A/C

4- iris is pushed forward

Incidence

1- Age : 5th to 6th decade

2- Sex : Women more effected

3- Bilateral but one’s eye is evolved first

Page 14: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Symptoms :

1- sudden onset & intense unbearable pain

2- Severe headache , nausea , & vomiting

3- marked deminshition of vision

4- redness , lacrimation , & photophobia

Signs :

1- chemosis

2- cilliary congestion

3- Cornea is cloudy

4- A/C very shallow

5- iris discolored , Atrophic patches

6- pupil is dilated and vertically oval

7- Glaucoma flakens (Psudu xexophalations )

8- markedly raised intocular pressure

9- fundus examn – difficult to see ( no cupping )

10- Gonioscopy narrow angle of A/C

11- the other eye has shallow A/C and narrow angle

Page 15: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Treatment : initial treatment is always medical & after controlling of IOP surgical peripheral iridectomy or laser iridotomy .

Page 16: Galucoma The most of important factor which cause rise of intraocular pressure is obstruction to the drainage of the aqueous humor

Absolute Glaucomathe eye is completely blind with markedly increased IOP

Treatment :

1- trabeculectomy

2- Cyclodialysis

3- Cyclocryopexy

4- to relive pain by retro bulbar alcohol injection
